SPECIFICATION forming part of Letters Patent No. 398,466, dated February 26, 1889.

Application filed Angus. 6, 1887' Serial No; 246,336- (No model.)

To all whom may concern:

Be it known that I, BENJAMIN F. STEWART, a citizen of the United States, and a resident of New Philadelphia, county of Tuscarawas, State of Ohio, have invented a new and useful Improvement in Grain-Binders, of which the following is a full, clear, and eXact description, reference being had to the accoin- 1 panying drawings, making part of this specification.

My invention relates to improvements in grain-binders; and it consists of the parts and combination of parts, as hereinafter described, and set forth in the claims.

Figure 1 is aview of the binder-frame from the stubble side, showing the actuating 1neohanism attached thereto. Fig. 2 is an elevation of internal gearavlreel, showing position of driving-pinion. Fig. 3 is a view in perspective of the drivingpinion and pawl. Fig. 4 is a view in perspective of driVinga-atchet. Fig. 5 is an elevation of the pawl-carrier, showing pawl and spring. Fig. 6 is an isometrical view of the binder-frame, showing the top and rear of frame and manner of con necting actuating mechanism. Fig. 7 is a front end elevation, and Fig. 8 is a rear end elevation. Fig. 9 is a detail view showing the lever K in several different positions. Fig. 10 is a detail view showing the parts I and J out of gear, the shaft D resting in the depression I) of the groove a Similar letters of reference represent corresponding parts in all of the figures of the accoinpanying drawings.

Letter A represents the binder-frame, hav- 1 ing on its horizontal branch laterally-projected lugs a, as a support for the needle-shaft B, and laterally-projected lugs a, as a support for the swinging frame O, in which the packei sliait D is journaled, and hangers a by which the binder-actuatin shaft E is supported. On the vertical portion of the said frame A there is provided a journal-box, a for the support of the pivoted loop (1 The upper horizontal portion is in pipe for1n,having journal-bearings at each of its ends for the knottershaft F. A shaft, G, is passed through the lugs a and the pipe portion 0 of the frame O, by which saidframe has a pivotal or swinging connection with the frame In the lower portion of the frame C there is provided a join-nal-support, c,.for the inner end of the packer-shaft D, on the end of which is mounted and rigidly secured. thereto the ratchet head If, having inelosed the j ratchet a and loosely mounted thereon the driving pinion I, the inner pawl, a, adapted Ito engage the ratchet a the extreme end of the shaft 1) resting in the groove a in wheel J, the teeth a of the pinion I engaging the teeth a of the gearwheel J, which is mounted on the inner end of shaft E. The drivingpinion I is formed separate from the ratchethead H, in order that said. driving-pinion may .be allowed to lie idle while the packers are forming the bundle. As soon as the bunidle is formed the pinion I will be thrown into gear with the ratchehhead II, as will hereinafter appear. On the inside of the groove a there is provided a notch, b, of such depth as will disengage the teeth of the pinion I from the wheel J when the notch b is brought opposite the shaft D, the spring I) and bolt supported in a suitable hanger depending from the lower branch of the frame and connected with the swinging frame O,

; drawing the frame O toward the center of wheel J, the shaft D passing into the depres sion Z), the pawl Z2 resting on a squared portion, 12 of the end of. shaft E, as shown in Fig. 8.

The pawls a" and b are constructed as shown, and connected. together or formed integral to operate simultaneously, so that when i the pawl b is pressed against the squared 5 portion or stop it will force the pawl a toward the center of the shaft out of engagement with the ratchet a but when the pawl 19 is disengaged from the squared portion or stop If it will, through the action of a suitable spring, as shown, drop between the stop and the face of the wheel I, and at the same time throw the pawl a into position to engage the ratchet a On the end of shaft E there is mounted a crank, b, and on the end of shaft B a similar crank, These cranks are connected by a link, I), substantially as shown, the length of the crank If being regulated to determine the rotation of shaft 15, and hence the desired. throw of the cord-arm or needle, usually about one-third of a revolution.

On the outer end of the knottcnshaftF there is mounted a crank, h, to the outer end of which. there is pivotally secured a difi'erential crank, '0 by which the difference between the circle described by the end of driving-link K and the crank. b may be compensated, the said link passing through a pivoted loop, a, and connecting the cranks Zr and D the said loop (0 having a supportingspindle that is passed through and rotated in the journal-box. (0'' provided therefor.

From the back of wheel J there is provided a spindle, (I, having mounted loosely thereon a roller, (1', and on the one end of shaft G there is securely mounted a cam, (Z and on the other end a supporting-arm, d", for the bundle-supporting finger The arm (Z is held in horizontal position and the cam vertically, as shown in Fig. 5, by the spring (1 and bolt supported on suitable bearings depending from the lower branch of the frame A and connected with the arm (i The vertical finger (Y may be adjusted on the arm (1 as shown.

A compressor, L, is provided,having its inner end pi votally secured to the binder-frame, as shown at (i and to operate the said. conipressor a roller, (1, is loosely mounted on a pin projected from the needle-arm M, as shown in Fig. 8, and when the needle is raised up to the knotter the roller (Z will engage the compressor, and its free end will be raised up to compact the sheaf.

The double-cranked packer-shaft D is of the usual form, and may be rotated by any of the well-known and approved ways that will permit the inner end to swing with the frame 0, as hereinbefore described.

The packers N are connected to the cranks h by j ournal-boxes h. The tail of the packer is supported on links 71 the upper end of which is supported by a collar or ring, h embracing and vibrating about the needleshaft B.

V The operation is as follows: The cut grain is gathered and packed between the packers N and the vertical finger d and compacted to a degree that will finally, when the sheaf reaches the desired size, produce sufficient pressure against the packers to move the shaft 1) over, disengaging the pawl 11 from the stop if", and engaging the cogs a of the driving-pinion I with the cogs a" of wheel J, and the pawl a with the ratchet a by which said wheel will be rotated. The pawl b passing down between the stop I)" and the pinion,will hold the pinion in engagement with the wheel while the end of the shaft D moves along in the groove a Three revolutions of the pi nion to one of the wheel bring the parts back to the position i'roin which they started. The roller d of the needle-arm will raise the compressor at the proper time to compact the sheaf, and the roller (1, throwing up the cam positions, as shown in Figs. 1

to fall back into its position to'receive another sheaf, and the action of the spring (1 will return the arm (1" and cam (Z into their normal and R. The same movement of the wheel J just described will rotate the shaft E, and with it the crank 11', which, through the link-commotion Z) to crank I), will cause shaft B to make about one-third of a revolution, or so much as may be necessary to throw the needle to the proper place, while the revolution of the crank I)", through the connecting-link K and fulcrum a", the link starting in the direction of the arrow, will revolve the knotter-head shaft F. The movement through the last quarter of the revolution will be accelerated by the position of the link K in the loop aflthe forward and downward movement of the crank b 0011- nected at that period of time to the short end of the link K, which during the same period of time acts as a lever as well as a link, the dilferential crank 11 equalizing the movement of the parts, so as to providea continuous rotary movement to the shaft F, and thereby to the knotting mechanism. The advantage gained by the increased speed of the shaft F, which carries the ejector, is that it accelerates the discharge of the sheaf, and to eject it with such force as to free it from entangle ment with the machine or grain therein.

Having thus fully described the nature and object of my invention, what I claim as new,

and desire to secure by Letters Patent, is-

1. A binder-frame, A, consisting, essentially, of a lower horizontal portion and an up right portion projected therefrom, the lower horizontal portion being provided with shaftsupports projecting laterally therefrom in opposite directions, and with a hanger depend ing from said horizontal portion, and the up right portion being provided at a point above the horizontal portion with a journal projecting laterally therefrom, substantially as set forth.

2, The frame A, having the shaft-supports a a a at extending laterally from its lower horizontal portion, the hangers a a depending from said horizontal portion, and the j ournal a projecting laterally from its upright portion, substantially as set forth.
